We emigrated along with the Prophet (صلى الله عليه وسلم) for the sake of Allah, so our reward was ensured by Allah. Some of us died without accumulating any material possession, like Mus’ab Ibn ‘Umair (رضي الله عنه) , while others gained rewards. Mus’ab Ibn ‘Umair (رضي الله عنه) died during battle of Uhud and we could not find anything to shroud him in besides his cloak. When we covered his head, his feet were exposed, and when we covered his feet, his head was exposed. So the Prophet (صلى الله عليه وسلم) instructed us to cover his head (with his cloak) and cover his feet with twigs.
